Description
- The present invention relates to a rod connector according to the preamble of
claim 1. Such rod connector is used for supporting a bone connection rod which connects bones, for example, a breast bone, a lumbar vertebra or the like. More particularly, the invention relates to a rod connector structured such that a connector main body supporting the rod freely swings with respect to a shank portion attached to an implant, for example, a screw or the like. - A rod connector of the above type is known from the document
US-A-5,584,831 . A related device is known from the documentUS 668 546 A5 . - As shown in
Fig. 1 , in a conventional bone connecting method, a plurality of screws (implants) 103 is screwed in to a lumbar vertebrae, and eachscrews 103 is supported by arod 105 each other. And aconventional rod connector 107 interconnects thescrews 103 and therod 105. - As shown in
Fig. 2 , theconventional rod connector 107 is comprised of a connectormain body 113 integrally formed in a distal end of ashank portion 109 supported by a head portion of thescrew 103. The connectormain body 113 is provided with arod insertion hole 111 allowing to freely insert the rod 105 (shown inFig. 1 ) and alocking screw 115 for pressure fixing therod 105. - According to the structure mentioned above, even in the case that a position of the
screw 103 is slightly displaced, it is possible to fine adjust the position of therod connector 107 by adjusting a position of theshank portion 109 and a rotation of theshank portion 109 around an axis thereof with respect to thescrew 103, whereby it is possible to properly support therod 105. However, therod connector 107 can be adjusted with respect to thescrew 103 only in a range that theshank portion 109 can rotate. Accordingly, there is a problem that an adjustable range is small. - Further, according to
Japanese Patent Application Laid-Open No. 11-318932 rod connector 107 of the related art mentioned-above is constituted by a plastically deformable member, and a rod is properly supported by plastically deforming the connection device. - In this case, there is also a problem that a freedom of adjusting the rod connector with respect to the screw is small.
- The present invention is made by taking the problems mentioned above into consideration, and an object of the present invention is to provide a rod connector in which a position adjustable range is large. To attain this object, a rod connector according to the present invention comprises the features of
claim 1. - Preferred embodiments are claimed in the subclaims.

Fig. 5B is a partly enlarged view ofFig. 5A ; and -
Fig. 6 is a plan view of the rod connector according to the embodiment of the present invention. - With reference to
Figs. 3 and4 , arod connector 1 according to an embodiment of the present invention is provided with ashank portion 3 having a circular cross sectional shape and supported to a U-shaped engagement groove formed in an upper portion of a screw (an implant) S being screwed into a vertebra body (not shown). A rear end portion of theshank portion 3 is provided with a flange portion 5 (a come-off prevention means) for preventing therod connector 1 from coming off from the U-shaped engagement groove of the screw S in an axial direction. - A connector
main body 11 is swingably attached to a distal end portion of theshank portion 3. The connectormain body 11 is provided with arod supporting portion 9 having a circular arc curved shape and supporting a rod 7 for a bone connection connecting vertebra bodies. In more detail, the connectormain body 11 is comprised of abase body portion 11A being vertically attached to theshank 3, protrudingportions base body portion 11A approximately, and has an approximately C shape. Further, arod supporting portion 9 is formed on an opposing surface in which the protrudingportion 11C opposes to the protrudingportion 11B. - In order to pressure fix the rod 7 to the
rod supporting portion 9 , arod pressing member 15 provided with arod pressing portion 13 having a circular arc curved surface and opposing to therod supporting portion 9 is attached to the connectormain body 11 so as to freely move in a direction moving apart from and close to therod supporting portion 9. - In more detail, a
through hole 17 penetrating in a horizontal direction inFig. 4 is formed in thebase body portion 11A, and abase portion 15A of therod pressing member 15 is engaged within the throughhole 17 so as to vertically move. Further, aspherical body portion 19 formed in a distal end portion of theshank portion 3 is attached to the throughhole 17 . Further, a pair of engagement recessportions base body portion 11A of the connectormain body 11 corresponds to thespherical body portion 19, and a portion in which thebase portion 15A of therod pressing member 15 corresponds to thespherical body portion 19 in an opposing manner. Thespherical body portion 19 is swingably attached to the pair of engagement recessportions - Accordingly, in a state in which the
spherical body portion 19 of theshank portion 3 is lightly clamped by the pair of engagement recessportions main body 11, it is possible to swing the connectormain body 11 in a desired direction with respect to theshank portion 3. On the other hand, when the pair of engagement recessportions spherical portion 19, the connectormain body 11 is fixed to theshank portion 3. - In order to clamp and fix the rod 7 by the
rod supporting portion 9 and therod pressing portion 13, and clamp and fix thespherical body portion 19 by the pair of engagement recessportions portion 11B is provided'with apressure fixing device 23 for pressing and fixing therod pressing member 15 in a direction of therod supporting portion 9. As one embodiment of thepressure fixing device 23, in the present embodiment, a fixing screw freely pressing therod pressing member 15 by a distal end thereof is screwed into the connectormain body 11. - Accordingly, the rod 7 can be fixed and supported by the
rod supporting portion 9 and therod pressing portion 13, by fastening the fixing device (the pressure fixing screw) 23, and the connectormain body 11 can be fixed to theshank portion 3. - In order to fix and support the rod 7, small
convex portions rod supporting portion 9 and the rod pressing portion 13 (both end sides of the rod 7 in a longitudinal direction), as shown inFig. 5B . Further, a supportingsurface 9a is provided between theconvex portions Fig. 5B shows only thesmall convex portion 25 of the rod supporting portion 9). In the same manner as the supportingsurface 9a, a supportingsurface 13a is provided between the convex portions(not shown). These supportingsurfaces - Accordingly, when the rod 7 is firmly clamped and gripped by the
rod supporting portion 9 and therod pressing portion 13, and a stress is concentrated near a distal end by the sharp distal end of the smallconvex portions 25, so that the distal end of theconvex portions 25 eats into the surface of the rod 7 so as to generate a scratch, and the supportingsurface 9a(13a) of the rough surface is brought into contact with the rod 7. Therefore, it is possible to prevent the rod 7 from moving in the axial direction and it is possible to prevent the rod 7 from rotating around an axis thereof. - In this case, in some difference in diameter of the rod 7, there is a case that the engagement state between the engagement recess
portions main body 11 and therod pressing member 15, and thespherical body portion 19 of theshank portion 3 is slack, at a time of firmly gripping and fixing the rod 7 by therod supporting portion 9 and therod pressing portion 13 . Further, on the contrary, there is a case that the clamping and fixing state of the rod 7 by therod supporting portion 9 and therod pressing portion 13 becomes slack, in a state in which the engagement state between both the engagement recessportions 21 and thespherical body portion 19 is a firm fixing state. - In the case mentioned above, the
rod supporting portion 9 is replaced by the connectormain body 11 formed in the circular arc curved surface corresponding to the diameter of the rod 7, and therod pressing portion 13 is replaced by therod pressing member 15 formed in the circular arc curved surface corresponding to the diameter of the rod 7, whereby it is possible to simultaneously achieve a clamping and fixing of the rod 7 and a fixing and integrally forming of the connectormain body 11 with respect to thespherical body portion 19 of theshank portion 3. In other words, it is possible to correspond to various rods 7 having various diameters by replacing both of the connectormain body 11 and therod pressing member 15 with respect to theshank portion 3. - According to the rod connector of the present embodiment, it is possible to adjust a position of the
shank portion 3 in an axial direction with respect to the screw screwed into the vertebra body so as to fix, and it is possible to adjust swing and rotation of the connectormain body 11 in a desired direction with respect to theshank portion 3 so as to fix. - Accordingly, even in the case that an adjusting freedom of the rod connector is large with respect to the screw screwed and fixed to the vertebra and a slight displacement is generated in the screw fixing position, or even in the case that the rod 7 has a curve, an incline or the like, it is possible to easily correspond thereto, and it is possible to always property support and fix the rod 7, so that the conventional problems mentioned above can be solved.
